ABSTRACT:
Scrap bars of extruded goods are reclaimed as billets for extrusion. An external force is applied to an aggregate of scraps, in which the scraps are piled in the form of a bundle having a predetermined length, so as to reduce its size in directions perpendicular to the longitudinal axes of the scrap bars, thereby forming a billet. The extruded goods produced from the billet have almost no pores and are not inferior to those produced from cast billets.
